A single Dick Johnson Racing Mustang is running at the Ipswich circuit along with the two brand-new Triple Eight Race Engineering Camaros and the Matt Stone Racing Camaro of Cameron Hill, who is undertaking a rookie test day.
A spokesperson for DJR, the Ford homologation team, was not in a position to shed any light on the matter when contacted by Speedcafe, on the basis that it is a Supercars test.
It is understood, though that the test is engine-related.
UPDATE: DJR testing multiple Ford engine specs
Both aerodynamics and engines have been the subject of off-season parity work, including historic category wind tunnel testing in North Carolina in December and earlier this month.
Torque sensors are one plank of Supercars’ bid to ensure parity between the 5.4-litre, Coyote-based double overhead cam unit which powers the Mustangs and the 5.7-litre pushrod ‘LTR’ which sits under the bonnet of the Camaros.
The other is transient dynamometer running, which is expected to begin in the United States before the start of the new season, on February 23 at Mount Panorama.
A number of Supercars technical staff are in attendance today at Queensland Raceway, although new General Manager of Motorsport, Tim Edwards, has not been sighted thus far.
